Different protein sources vary in their ability to stimulate muscle protein synthesis and support anabolism based on quality scores like DIAAS.

Pork sausage and plant-based substitutes show different DIAAS values and varying limiting amino acids such as leucine, sulfur-containing amino acids, or lysine.

Plant proteins often suffer from imbalanced amino acid profiles and reduced digestibility, distinguishing them from complete animal-derived proteins.
